HOW TRUMP IS HANDLING LAS VEGAS:From POLITICO’s Annie Karni: “President Donald Trump’s reaction to the country’s deadliest mass shooting — a somber statement from the Diplomatic Room, a moment of silence on the South Lawn, and a dormant-for-a-day Twitter feed — didn’t make a tragic situation worse. The president’s words and actions, Democrats and Republicans said, were in line with what any other National Rifle Association-backed president would do. Trump’s call for unity in the face of ‘an act of pure evil’ was accompanied by a day declared by his team to be a no-go zone for political or policy discussions about the nation’s gun laws. For the first nine months of his presidency, most of the crises Trump has faced have been of his own making. But the shooting, which killed at least 59 and injured more than 500 Las Vegas concert-goers Sunday night, presents a new kind of leadership test. In the coming days, as the window of a condolences-only response to a domestic tragedy closes, Trump will be forced to navigate a thorny political situation as he reacts to the first mass shooting to unfold on his watch. Mass shootings in America have become moments of national reckoning on immigration, terrorism and bullying. In this case, where the shooter had no clear motive, the discussion quickly turned to the one subject Trump and his advisers steered clear of in their first 24-hours of response: gun safety measures.”

TRUMP’S TRIP TO PUERTO RICO:From POLITICO’s Matthew Nussbaum: “President Donald Trump on Tuesday will come face to face with the ‘politically motivated ingrates’ he slammed on Twitter just days before. The president will land in Puerto Rico after spending much of the past week boasting about a wildly successful response effort that hasn’t matched the reality of the hurricane-ravaged island and after picking a fight over the weekend with the San Juan mayor. The visit comes as he’s also attempting to be soother-in-chief for the nation after a shooting in Las Vegas left at least 59 dead on Sunday night — the first time he’s had to navigate two disasters of national scope that are politically perilous for any president, but especially one prone to off-the-cuff riffs. The Puerto Rico stop will mark only the start of emotionally charged travels for Trump this week. On Wednesday, he is scheduled to travel to Las Vegas to meet with the families of victims of Sunday’s massacre. Trump struck a somber tone in his first public comments on the deaths in Las Vegas, decrying the ‘act of pure evil’ and calling for unity. On Tuesday, though, he will trade the scripted and controlled setting of the East Room for a storm-ravaged island where more than half of the residents remain without access to drinking water and only 5 percent of the island has electricity.”

EMAILS: From POLITICO’s Josh Dawsey and Andrea Peterson of the Project on Government Oversight: “White House officials have begun examining emails associated with a third and previously unreported email account on Jared Kushner and Ivanka Trump’s private domain, according to three people familiar with the matter. Hundreds of emails have been sent since January from White House addresses to accounts on the Kushner family domain, these people said. Many of those emails went not to Kushner’s or Ivanka Trump’s personal addresses but to an account they both had access to and shared with their personal household staff for family scheduling. The emails — which include nonpublic travel documents, internal schedules and some official White House materials —were in many cases sent from Ivanka Trump, her assistant Bridges Lamar and others who work with the couple in the White House. The emails to the third account were largely sent from White House accounts but occasionally came from other private accounts, one of these people said. The existence of additional accounts on the family domain beyond the two personal accounts used by Kushner and Ivanka Trump and reported earlier raises new questions about the extent of personal email use by the couple during their time as White House aides. Their use of private email accounts for White House business also raises concerns about the security of potentially sensitive government documents, which have been forwarded to private accounts.”

WELFARE WATCH:From POLITICO’s Andrew Restuccia: “Trump administration officials are mulling an executive order that would instruct federal agencies to review low-income assistance programs, part of a coming effort to make sweeping changes to the country’s welfare system. The White House began circulating a draft order to federal agencies for comment last week, according to two administration officials, who were granted anonymity to discuss the internal deliberations.”
